De-risk SiC Supply in 2025: High-Throughput Burn-In and ATE for Pakistan’s Industrial Power Platforms

Omdat de textiel-, cement- en staal sectors adopt Silicon Carbide (SiC) across UPS, VFD front-ends, STATCOM/APF, EV charging, and high-reliability PSUs, rigorous reliability screening is essential. SiC devices operate at high dv/dt and elevated junction temperatures up to 175°C, making early-life defect removal and parameter monitoring critical to prevent field failures on weak grids. Silicon Carbide Device Burn-In and Automated Test Equipment (ATE) from Sicarb Tech provides production-grade screening and qualification: HTGB/HTRB/HTOL burn-in, dynamic switching stress, avalanche and UIS testing, and automated parametric characterization (RDS(on), Vth, Qg, Coss, body diode, leakage) with full traceability.

Sicarb Tech’s platform integrates high-temperature ovens, programmable SMUs/loads, isolated high-CMTI gate drive fixtures, and safety interlocks, all orchestrated by analytics that flag drift and outliers. Backed by the Chinese Academy of Sciences, we offer equipment supply, process recipes, and technology transfer to establish local test lines in Pakistan’s SEZs—shortening lead time and ensuring consistent quality for 2025 buildouts.

Why Production-Grade SiC Burn-In and ATE Outperform Ad-hoc Lab Testing for Industrial Reliability

Reliability and throughput outcomes	SiC burn-in + automated ATE (production-grade)	Basic lab test benches	Practical impact for Pakistan deployments
Early-life failure screening	Systematic HTGB/HTRB/HTOL + drift analytics	Limited soak/spot checks	Fewer field failures and recalls
Dynamic ruggedness validation	Automated double-pulse, UIS, EAS, SC SOA	Manual or omitted	Confidence in weak-grid events
Throughput and repeatability	Parallel channels, fixtures, recipes	Low throughput, operator variance	Predictable lead time, lower cost
Traceability and compliance	Full genealogy, SPC, COA	Minimal records	Faster NTDC/utility audits
Safety and coverage	Interlocks, HV management, arc detect	Ad-hoc protections	Reduced lab risk, consistent results

Belangrijkste voordelen en bewezen voordelen

• Lower DPPM and warranty risk: Early-life defects are eliminated, and drift is monitored, cutting field returns and downtime in harsh, hot environments.
• Validated dynamic robustness: UIS, avalanche, and dv/dt testing prove survivability under sags, surges, and fast transients common on weak feeders.
• Faster time-to-approval: Automated reports align with IEC/IEEE expectations, simplifying EPC and utility sign-off.
• Scalable and localizable: Equipment and recipes can be installed in Pakistan to reduce logistics delays and currency exposure.

Veelgestelde vragen en antwoorden van experts

• What burn-in duration is recommended?
  Typical programs use 48–168 h depending on risk tolerance and application; we tailor profiles by device family and field data.
• Do we need UIS and avalanche tests for all devices?
  For inverter legs exposed to grid transients, UIS/EAS add confidence; for rectifiers-only roles, reduced dynamic testing may suffice.
• How is dv/dt ruggedness verified?
  Through double-pulse tests with high-CMTI drivers and layout-accurate fixtures to emulate real switching loops.
• Will screening affect device lifetime?
  When correctly profiled (current/temperature margins), screening removes early failures without accelerating wear-out; we validate via HTOL/Arrhenius models.
• Can you integrate with our MES/ERP?
  Yes—our ATE software supports REST/OPC-UA interfaces and generates digital COAs and SPC reports.
